ELE3804 Power Systems Protection
|Semester 1, 2019 Online|
|Short Description:||Power Systems Protection|
|Faculty or Section :||Faculty of Health, Engineering and Sciences|
|School or Department :||School of Mechanical and Electrical Engineering|
|Student contribution band :||Band 2|
|ASCED code :||031301 - Electrical Engineering|
|Grading basis :||Graded|
Examiner: Andrew Hewitt
Pre-requisite: ELE1801 or Students must be enrolled in the following Program: GCEN
Modern society cannot function without a reliable supply of electricity. However, an electrical power system that is completely free from failure is neither economically justifiable nor technically feasible. A power system or some part of the power system will, under certain abnormal circumstances, become faulted and as a result cease to operate as intended. A protection system, in the event of a fault, is required to maintain safety of personnel and members of the public, minimize damage to the power system, minimize interruption of supply and help maintain quality of supply. This course will help students develop the skills needed to design and carry out performance analysis of protection systems.
The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:
- Explain the principle of operation of components used for implementing protection systems;
- Identify the key factors that influence the design of typical protection systems;
- Carry out quantitative analysis of the performance of typical protection systems;
- Devise protection schemes that are appropriate for particular applications.

Important assessment information
There are no attendance requirements for this course. However, it is the students' responsibility to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.
Requirements for students to complete each assessment item satisfactorily:
To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.
Penalties for late submission of required work:
Students should refer to the Assessment Procedure http://policy.usq.edu.au/documents.php?id=14749PL (point 4.2.4)
Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the weighted marks available for that assessment item.
Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.
To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure http://policy.usq.edu.au/documents/14749PL (point 4.4.2).
Method used to combine assessment results to attain final grade:
The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.
In a Closed Examination candidates are allowed to bring only writing and drawing instruments into the examination.
Examination period when Deferred/Supplementary examinations will be held:
Any Deferred or Supplementary examinations for this course will be held during the next examination period.
University Student Policies:
Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at http://policy.usq.edu.au.
Students must familiarise themselves with the USQ Assessment Procedures (http://policy.usq.edu.au/documents.php?id=14749PL).
Referencing in Assignments must comply with the Harvard (AGPS) referencing system. This system should be used by students to format details of the information sources they have cited in their work. The Harvard (APGS) style to be used is defined by the USQ library’s referencing guide. These policies can be found at http://www.usq.edu.au/library/referencing
